How to Turn Long Videos into Shorts

Choose a source you can reuse

Start with a video file or a supported public YouTube video or Twitch VOD. You need permission to process and reuse the footage. A public link does not grant those rights, and a link can still fail when its source is restricted, unavailable, or protected.

To repurpose long-form video, first find moments that can stand alone, then shape each one for a short-form viewer. Cutting the recording into equal intervals skips the selection and often leaves clips without a point.

1. Open the intoshort dashboard and choose a video file or paste a supported public video link.
2. For a link, wait for the source preview, then continue to the clip settings. For a file, check its name and preview in the configuration dialog.

Decide what makes a moment worth keeping

Choose the kind of passage that suits the source. An interview may contain a complete answer, a stream may have a reaction and the event that caused it, and a tutorial may have one useful explanation. Add context about the topic or audience when it helps guide the search.

In intoshort, choose Strongest overall or one or more moment categories such as Funny, Surprising Facts, or Stories. These categories are alternatives. A passage can fit one category without fitting the others. Set a duration and a target count, or leave the count on Auto. A target guides the search; it does not guarantee that the source contains that many strong clips.

1. Choose the moment types, target duration and desired clip count, then enable captions if you want them in the first renders.
2. Select Generate and follow the processing stages on the video page. For a local file, keep the tab open until its upload is confirmed.
3. When the drafts are ready, play each short before deciding which ones to edit or export.

Check the setup, payoff, and meaning

For example, imagine a creator saying, 'We replaced the camera because the old one overheated during every stream.' A cut that starts at 'the old one overheated' may leave a new viewer asking what changed. Including the sentence about replacing the camera gives the short a clearer setup. This is an illustrative example, not a result from an intoshort job.

Play each proposed passage from beginning to end. Keep enough context to explain the event or answer, and listen just beyond the cut to make sure you have not removed a qualification. Remove repeated or weak suggestions instead of filling the requested count with clips that do not stand alone.

1. State the point of the clip in one sentence.
2. Watch it as if you have not seen the source video.
3. Keep the shortest setup that makes the point understandable.
4. Check that the ending preserves the speaker’s meaning or the event’s outcome.

Choose a format and check the framing

Choose a 9:16 vertical export for a full-height short, then review what the crop keeps in frame. A horizontal source may need a centered crop, a blurred background, or a gameplay and facecam layout when the source supports it. The automatic layout can fall back to a centered crop when facecam detection is absent or unstable, so inspect the result scene by scene.

If vertical framing hides useful gameplay or a second person, consider whether a different layout or a 16:9 export better serves the passage. A vertical frame is a format choice, not a reason to lose the detail that explains the clip.

Review captions before exporting

Check caption wording against the audio, especially for names, numbers, game terms, and short words that can change a sentence’s meaning. Adjust the caption style, size, margins, or position if the text covers a face or important on-screen action. Captions can make speech easier to follow, but they cannot restore missing context or correct an unclear source by guessing.

The editor works on an individual short. Save your cut and caption changes, wait for the new render, then watch that rendered version before downloading it. The export is not updated merely by previewing an edit.

Know what the first pass can miss

Transcript-led selection may miss a brief silent play, a visual joke, overlapping speech, or context that only appears on screen. Very long or high-resolution sources can also take more time to process, and poor audio can reduce transcription quality or stop the job.

Treat each suggestion as an editable draft. Keep the original source, reject moments that do not work on their own, and export only the versions you have reviewed. Neither a requested clip count nor an AI selection guarantees a useful result or audience response.
